1 Claim. 1

The present invention relates to new and useful improvements in workholders designed primarily for use by painters for holding storm sash,screens or the like, in a convenient position while painting the same.

An important object of this invention is to provide a work holderincluding a clamp engaging the opposite side edges of the work and awall bracket pivotally supporting the clamp for turning the work into adesired position while painting the same.

A further object of this invention is'to provide an adjustable workholding clamp to accommodate storm sash or screens of various widths orsizes.

A still further object is to provide a device of this character insimple and practical construction, which is strong and durable,relatively inexpensive to manufacture and otherwise well adapted for thepurposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view showing a storm sash secured inposition in the work holding clamp; I

Figure 2 is a side elevational view;

Figure 3 is a top plan view;

Figure 4 is a front elevational view of the work holding clamp per se;

Figure 5 is a longitudinal sectional view thereof;

Figure 6 is an enlarged side elevational View of the resilient abutmentfor the work carried by the clamp; and,

Figure 7 is an enlarged perspective view of the wall bracket.

Referring now to the drawings in detail, wherein for the purpose ofillustration, I have disclosed a preferred embodiment of the inventionthe numeral 5 designates the work holding clamp generally and whichcomprises a pair of telescopically connected tubes 6 and 1 secured inextensible position with respect to each other by means of- 2 V posedends l4 and hand gripping bars l5 at their outer ends.

One or more pivot pins l6 are threaded in the tubular member 6 toproject rearwardly therefrom for selective insertion in an opening orbore l1 extending longitudinally in a block [8 suitably secured on thelower horizontal leg l9 of an L-shaped wall bracket 20 which is formedwith a pair of key hole slots 2| in its vertical leg 22 for receivingheaded pins 23 projecting from a wall or other suitable verticalsupporting structure 24. A resilient abutment or stop 25 of strap metalis welded or otherwise secured at its central portion to a collar 26slidably mounted on the tubular member 6 and with the ends of theabutment or stop 25 curved forwardly and outwardly. as shown at 21. Thecollar 26 is secured in adjusted position on tubular member 6 by meansof a thumb or set screw 28.

In the operation of the device the tubular members 6 and I are adjustedto position the forwardly projecting arms l0 and II from each other theapproximate width of the Work 29, such as a storm sash or window screenwhich is engaged substantially at its central side portion by thepointed ends M of the clamping screws l2 and I3 and with the abutment orstop 25 positioned behind the work at one side thereof to preventswinging or tilting movement of the work in the work holding clamp. Oneof the pivot pins I6 is then inserted in the opening I! of the Wallbracket 20 to balance the work holding clamp 5 with the work 29 thereinon the wall bracket.

The outer surface of the work 29 may then be painted or cleaned and uponcompletion thereof, the work holding clamp 5 is removed from the workand placed at the reverse side of the latter and again mounted in thewall bracket 20 for painting or cleaning the other surface ofthe work.

During the painting or cleaning of the work the work holding clamp 5 maybe turned on the pivot pin Hi to position the work in its mostconvenient position.

In view of the foregoing description taken in conjunction with theaccompanying drawings, it is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description is accordingly described and the scope of theappended claim.

as new is:

A work holder comprising a U-shaped clamp, said clamp being formed oftwo extensibly connected tubular L-shaped members, means on one of saidL-shaped members for rotatably suspending said clamp and a work piecetherein from a support, workfclamping screws which-are aligned withrespe'cfito each other: at? 10 Numbeg V the ends of the clamp forengaging the side edges of the work piece, means for releasably locking,

'on said one member, and astcn'carried collar and including a pair ofresilient amshawing free end portions. adapted to contact the workpieceon one surfaceithereof. to prevent. .110-

tative movement of the workpiece about the axis 01' said screws.
